The schubert is light 1.7kg the shoei lighter 1.5kg. Asfar as fitting you will only know by trying it on. I think it mat be a little rounder than my caberg as there seems a little more pressure on the forehead. I have a dealer fairly local so easy to try on but his are priced to high, there are a couple of internet dealers in uk who will collect lid for free if size doesent suit, others dont so best check if buying onlie wthout trying.
Getting a schuberh for my wife soon, I would love one also but £600 is a big chunk of cash in one go.
